Answer / nishat

Race around condition happens when output triggers a change in output(here output is a feedback e.e JK flipflop).A change in output may change the output again and again before it settles..... making the output indeterminate and toggle in the same clock pulse.
Toggling is when a particular input give different outputs different times.The output changes in different clock pulses.
